Typescript Compiler error TS2307: Cannot find module 'jquery'

Question

I was following JSPM getting started guide and I want to install jquery package so I execute below command.

jspm install jquery

But when I try to import it in typescript like below

import $ from 'jquery'

I'm getting a error from typescript compiler saying error TS2307: Cannot find module 'jquery'. Not only for this library for other libraries I'm getting the same error.

Answer 1

您需要在编译上下文中包含jquery类型定义，您可以从https://github.com/DefinitelyTyped/DefinitelyTyped获取它们

Answer 2

I encountered on exactly same kind of error during VSBuild on Azure DevOps.

In my case, solution was just add new extra step Install npm into build pipeline and error was gone.

I hope it will help somebody!
